Abstract
The utility model relates to an automotive adjustable muffle. The utility model is characterized in that an existing muffler, additional mufflers and valve gates are organically combined; namely, the adjustable valve gates and additional mufflers are arranged on the front and the rear ends of the existing muffler, and the resistance force and the muffling quantity of the muffler can be adjusted according to requirements. The muffler has the advantages of simple structure and convenient operation, solving the problems that the starting noise and the resistance force can not be adjusted according to the environmental requirements; the muffling quantity can be increased significantly, and the engine power can be significantly improved particularly conditions.
Description
The utility model relates to a kind of for motor vehicle adjustable silencing apparatus.
Existing various silencing apparatus (also claiming conventional muffler), of a great variety; But they have a common drawback: unadjustable, promptly various silencing apparatuss use once producing, and technical parameters such as its sound deadening capacity, resistance can not be regulated according to environmental change and user's needs.
The purpose of this utility model is to provide a kind of adjustable silencing apparatus that overcomes above-mentioned defective.
The technical solution of the utility model is: referring to accompanying drawing 1, accompanying drawing is this acoustic wave filter structure principle schematic.From accompanying drawing as can be seen: adjustable silencing apparatus is that the front and back ends in conventional muffler (3) is provided with adjustable valve and additional silencing apparatus, between promptly additional silencing apparatus (1) and the conventional muffler (3) adjustable valve (8) is set, between conventional muffler (3) and the additional silencing apparatus (4) adjustable valve (7) is set, its additional silencing apparatus and conventional muffler are to link up by connecting tube (2), adjustable valve is arranged on the connecting tube (2), adjustable valve (8) is a normal closed gate, generally uses when needs increase power.Adjustable valve (7) is the normally open valve door, generally eliminates the noise in environmental requirement and just closes when effective, enables additional silencing apparatus (4), and reaches the effect of eliminating the noise preferably; Valve (7) is often opened at ordinary times, and its silencing apparatus technical parameter is identical with the technical parameter of existing silencing apparatus.Can establish operating handle (5) and Returnning spring (6) on adjustable valve (7), (8); Additional silencing apparatus (1) is arranged on the front end of conventional muffler (3), generally is designed to one-level expansion silencing apparatus, with the peak value that abates the noise.
Working principle of the present utility model: 1, throttle down (8), Open valve (7), at this moment, gas is discharged from valve (7), and its technical parameter is identical with the technical parameter of conventional muffler; 2, higher when environmental requirement, eliminate the noise when effective, close adjustable valve (7), (8), at this moment, the sound deadening capacity that its silencing apparatus is total:
△ P=△ P biography+△ P is attached
△ P---the sound deadening capacity that adjustable silencing apparatus is total; △ P passes---the sound deadening capacity of conventional muffler; △ P is attached---the sound deadening capacity of additional silencing apparatus.
3, when need increase engine power, Open valve (8), gas is discharged from valve (8), and its silencing apparatus can increase power;
△ P=△ P biography * n
△ P---the increasable power of adjustable silencing apparatus; N---power coefficient of reserve power; △ P passes---the power that conventional muffler consumes; That is to say that the increasable power of adjustable silencing apparatus equals the power that conventional muffler consumes.For example, select the CS492Q-1 diesel engine to test with JXQ series purifying muffler, its test result is as follows:
| Engine speed | Power (horsepower) | Improve power | ||
| Throttle down (8) Open valve (7) | Open valve (8) Open valve (7) | Horsepower | ％ | |
| 3200?r?p?m | 76.2 | 81.3 | 5.1 | 6.693 |
| 4000?r?p?m | 87.2 | 91.2 | 4 | 4.552 |
In sum, the utlity model has following advantage and effect: 1, simple in structure, easy to operate, can be directly or control cab by connecting rod open and close valve easily.2, solved the uncontrollable problem of silencing apparatus, silencing apparatus can be regulated according to the variation of environment or operator's requirement, both can increase the sound deadening capacity of silencing apparatus significantly, special circumstances can improve engine power again significantly; As the carload climbing, the public security vehicle is carried out hot pursuit, particularly suitable when fire-fighting vehicle carries out an urgent task.
Claims (1)
1, a kind of for motor vehicle adjustable silencing apparatus, it is characterized in that being provided with adjustable valve and additional silencing apparatus at the front and back ends of conventional muffler (3), between promptly additional silencing apparatus (1) and the conventional muffler (3) adjustable valve (8) is set, between conventional muffler (3) and the additional cross-talk device (4) adjustable valve (7) is set, its additional silencing apparatus and conventional muffler (3) are to link up by connecting tube (2), and adjustable valve is arranged on the connecting tube (2).
